This is, beyond a doubt, the worst calculator I have ever seen. Having had a body composition analysis done, I know my current lean mass weighs 114 pounds. In order to weigh the 99 to 121 pounds this calculator suggests…I would have to lose muscle, lots of muscle.


    Since you had a body composition analysis done, you should know your percent body fat. The Healthy Body Calculator® is designed for average body fat people, not lean people. If you are lean, I would recommend you include your percent body fat next time you try my calculator. BTW, the Healthy Body Calculator® is based on current nutrition science and practice.

    If you would like to read additional information about the validity of body composition analysis methods like electrical impedance, skin fold calipers and underwater weighing, read the sports nutrition topic and search for electrical impedance.
